Tracker installed but cartrack cannot find details of my vehicle when requested.

A new tracker has been installed in my vehicle (I have technician work report as proof), when i requested my tracking details a year later, cartrack did not have any record of my vehicle. A mail from representative from Cartack said they need to install a new tracker again. Thus my company paid for a service/product which never worked, and for tax purposes i have no record of my traveling details. I could not get hold of the representative, and the online complains division could not resolve my issue, and the complaints division refused to provide me with a contact person details who can assist with my issue.
